Cloud ShareSync: Backup/ Replicate data between Synology NAS servers (Part2)

If you have two synology NASes  there are a lot of ways for you to backup your data.

You can backup your data using:

  1. File station : Drag and drop files between NASes
  2. Cloud Station ShareSync (this post): One/Two way sync for files and folders that change frequently in real time (hot storage).
  3. Shared Folder SyncOne way sync for files and folders that do not change that often (cold storage).
  4. Snapshot ReplicationSnapshots of your folders on specific periods of time.
  5. Hyper BackupData backed up are kept in a database which can be browsed, downloaded or restored with tailor-made multi-version explorer on DSM, Windows and Linux platforms.

In this post we will cover the Cloud Station ShareSync replication and in future posts, we will cover the rest of the backup/Replication features.

 Replication using Cloud Station ShareSync

What is Cloud Station ShareSync?

It is a one-way/two-way sync with file versioning, It allows shared folders and shared folder privileges to be replicated between a centralized Synology NAS and multiple Synology NAS servers with a simple setup. It is especially suitable for long-term replication of data requiring frequent modifications, since all changes made after the initial sync will be synced in real time.

In plain english:  everytime you modify, delete or copy a file in your master NAS it will make a copy LIVE to your slave NAS.

Configure the Master

According to NAS documentation, you need to install in the host server (the server you want to copy the data to others – I will call it the master in this post) the Cloud Station Server package.

I have Drive installed instead and I use the Drive Admin Console instead. Either one works.

To be able to replicate files and folders in another NAS, you need to enable them in either Cloud Station package or Drive Admin console. I am going to show you how to do it with Drive:

  1. Click on Team Folder
  2. Click on My Drive
  3. And then click Enable

Configure the Slave

For the slave, you need to install the Cloud Station ShareSync package:

  1. Go to Package center
  2. In the Backup Section
  3. Select Cloud Station ShareSync.

Once the package has been installed:

  1. you will see the icon in the top right corner and if you click on it,
  2. you will be able to configure it: “Launch Cloud Station ShareSync”

I have already installed it, so your dialogs might look a bit different, but the idea is the same.

First things first, connect to your remote NAS or master:

5

and connect you your NAS:

  1. Quickconnect or IP
  2. Username
  3. Password

6

And if you dont have the local folders created on your slave, make sure you do that before the next step.

The only thing left to do is to tell your Synology where you want your files copied.To do that:

  1. you go to Sharing
  2. Click enable on the folders you want to sync (click on the folder icon to select a folder on the slave)
  3. Folder on the master
  4. Folder on the slave
  5. Sync direction (set up down below)
  6. Status
  7. Settings (see below)
  8. 7

So, the settings (the wrench icon) are as follows:

For each sync folder, select the under folders you want to sync (if not all).

8

Select the file size and file type

9

And finally select if you want one or two way sync.

10And once you have done that, everytime you modify, delete or copy a file in your master NAS it will make a copy LIVE to your slave NAS.

Awesome!!

  1. Hi Ruth,

    Did you work with this solution in production environments?
    I’m experiencing problems with high amount of files and inconsistent synchronisations between locations.

    We use ShareSync because we have multiple locations and we work with larger files, so sync apps like Syno Drive or DropBox will result in computers with full disks.

  2. Ruth,
    we’re using Cloud station ShareSync in our office to sync machines from one physical office to another, but it is a two way sync.. no master/slave per se.. Yes, one is setup as as the server and the other client, but the synchronization is two way.

  3. I have two Synology NAS units. One in USA as the “master” and the other overseas as the slave. Actually setup for bidirectional sync. I frequently get synchronization errors in which the remote “slave loses synch. Synology suppler has not been able to help me and seem like they just do t care. To resync I need to manually go into DSM and uncheck the mapping for each folder pair, apply, recheck the mapping and reapply. It then synced and works for manybe a week or so.

    1. I had Bidirectional sync before, but I managed to delete an entire share folder on my master and it got deleted on my slave too!!
      Thankfully I had replication snapshots on so I only lost one day of data, but after that I only have one-direction as my slave is my backup.
      Take that into account!!
